The recent developments of energy storage devices are concerned with larger energy storage ability, low loss and good temperature stability. It has a great technological importance in engineering science. The dielectric materials like ceramics and glass ceramics have great interest in electronic ceramic industry due to above concern. The ceramic dielectrics are used as a capacitive element in electronic circuits. The perovskite glass ceramics have very high dielectric constant and low dielectric loss. The high dielectric constant in glass ceramics is attributed to space charge polarization. In order to produce glass ceramics of high dielectric constant, barium titanate glass ceramics is the first discovered ferroelectric perovskite. In this review article, we are summarizing the dielectric behavior of perovskite glass ceramics such as

“…Recently, many studies have been performed with respect to substitution with different heterovalent elements. Data have been reported in the literature regarding enhanced dielectric constant, [40] structural transformation, [41] and Curie temperature shifts [29] by employing various heterovalent substitutions. In one such particular study, Cai et al have reported suppressed dielectric losses in vanadium-doped BT bulk ceramics.…”

This study proposes to significantly improve the electrical energy storage characteristics of BaTiO3 bulk ceramics. Addition of 3 BaO–3 TiO2–B2O3 glass was done in controlled amounts to study its effect on the ferroelectric response and storage characteristics of vanadium‐doped BaTiO3 samples. The energy density for the composites was calculated using hysteresis loops. It was observed that a significant improvement in the energy storage density can be obtained by addition of 1 % (weight) 3 BaO–3 TiO2–B2O3 glass. The addition of glass in small amounts was also observed to impart additional benefits such as increased saturation polarization and a thermally invariant ferroelectric response.

YIG is useful for dielectric resonator antenna (DRA) but its narrow size of frequency bandwidth (0.38-0.44 GHz), negatively influenced the DRA performance. An investigation on Ce doped YIG through the conventional solid-state reaction based on the Y 3-x Ce x Fe 5 O 12 (Ce x ; x = 0-1.5) system was carried out. Outside the range of 0.1 B x B 1.0 where maximum solid solution could be achieved, a new impure phase of CeFeO 3 (CIP) to YIG was detected. Ce affected the sample microstructure and reduced the grain size of YIG. For the DRA measurement, the addition of Ce enhanced the bandwidth efficiency (BW %) up to 11.16 %. The radiation patterns of all the samples indicated the omnidirectional characteristic, which suggested that the signal could be received by this dielectric antenna in various positions. Therefore, Ce doped YIG successfully enhanced the operating frequency of the antenna and was suitable for the X-band frequency range applications.
